THERMAL ANALYSIS
The ADuM620x devices consist of four internal silicon die
attached to a split lead frame with two die attach paddles. For
the purposes of thermal analysis, the device is treated as a thermal
unit with the highest junction temperature reflected in the θ JA
value from Table 14. The value of θ JA is based on measurements
taken with the part mounted on a JEDEC standard 4-layer board
with fine width traces and still air. Under normal operating
conditions, the ADuM620x operates at full load across the full
temperature range without derating the output current. How-
Data Sheet
When the ADuM620x acts as a slave, its power is regulated by a
PWM signal from a master device. This allows multiple iso Power
parts to be combined in parallel while sharing the load equally.
When the ADuM620x is configured as a standalone unit, it
generates its own PWM feedback signal to regulate itself.
The ADuM620x devices can function as slave or standalone
devices. All devices in the ADuM5xxx and ADuM6xxx family
can function as standalone devices. Some of these devices also
function as master devices or slave devices, but not both (see
Table 25).
ever, following the recommendations in the PCB Layout section
decreases the thermal resistance to the PCB, allowing increased
thermal margin at high ambient temperatures.
INCREASING AVAILABLE POWER
The ADuM620x devices are designed to work in combination
with the ADuM6000 in a master/slave configuration. The RC IN
and RC SEL pins allow the ADuM620x to receive a PWM signal
from an ADuM6000 through its RC IN pin and to act as a slave to
that control signal. The RC SEL pin chooses whether the part acts
as a standalone, self-regulated device or as a slave device.
